The speckled longfin eel, Australian long-finned eel or marbled eel (Anguilla reinhardtii) is one of 15 species of eel in the family Anguillidae. It has a long snake-like cylindrical body with its dorsal, tail and anal fins joined to form one long fin. It usually has a brownish green or olive green back and sides with small darker spots or blotches all over its body. Its underside is paler.[1] It has a small gill opening on each side of its wide head, with thick lips. It is Australia's largest freshwater eel, and the female usually grows much larger than the male.[1][2] It is also known as the spotted eel.


Long-finned eels can grow to 1.6 metres and 22 kg (although generally to 1 metre) for females while males are much smaller at 650 mm and 600 g.[3] Landlocked eels have been reported to grow to 3 metres (10 feet).[2]


The long-finned eel is a native of New Guinea, eastern Australia (including Tasmania), Lord Howe Island, and New Caledonia.[1] It can be found in many freshwater areas, including creeks, streams, rivers, swamps, dams, lagoons, and lakes although generally more often in rivers than lakes.[2]
